Imaging evaluation of periprosthetic loosening: A primer for the general radiologist.

In response to an ageing global population, the primary hip and knee arthroplasty rate continues to increase. Although an effective treatment, up to 25% patients may require revision arthroplasty during their lifetime, commonly due to periprosthetic loosening. Revision procedures are associated with significantly increased healthcare costs; therefore, timely and accurate diagnostics are critical for clinicians and patients.

The impact of patient-reported factors of endoscopic screening experience on attendance at future examinations and distal colorectal cancer incidence.

Background: Endoscopic examinations can reduce colorectal cancer (CRC) burden through early detection and removal of precancerous lesions; however, after initial endoscopy, some patients do not attend subsequent examinations.

Aims: To investigate the impact of patient experience of endoscopic screening on attendance at future examinations and distal CRC incidence.

Methods: In a cohort study including 40,141 participants who received flexible sigmoidoscopy (FS) screening in the UK FS Screening Trial, median follow-up was 16.

Remote sensing for species distribution models: An illustration from a sentinel taxon of the world's driest ecosystem.

In situ observed data are commonly used as species occurrence response variables in species distribution models. However, the use of remotely observed data from high-resolution multispectral remote-sensing images as a source of presence/absence data for species distribution models remains under-developed. Here, we describe an ensemble species distribution model of black microbial mats (Nostoc spp.

Improving stroke pathway efficiency: outcomes of a quality improvement collaborative across a national stroke network.

Background: Timely endovascular thrombectomy (EVT) is crucial for improving outcomes in acute ischemic stroke (AIS). This study evaluated the effectiveness of a national quality improvement collaborative (QIC) in reducing process times for potential EVT candidates across a national stroke network.

Methods: A pre-post intervention design using a modified Breakthrough Series approach was implemented across 24 hospitals.

Soil Nitrogen Supply Exerts Largest Influence on Leaf Nitrogen in Environments with the Greatest Leaf Nitrogen Demand.

Accurately representing the relationships between nitrogen supply and photosynthesis is crucial for reliably predicting carbon-nitrogen cycle coupling in Earth System Models (ESMs). Most ESMs assume positive correlations amongst soil nitrogen supply, leaf nitrogen content, and photosynthetic capacity. However, leaf photosynthetic nitrogen demand may influence the leaf nitrogen response to soil nitrogen supply; thus, responses to nitrogen supply are expected to be the largest in environments where demand is the greatest.
